Expression Trees in C#
Expression trees are an advanced approach to creating code, both at design time and at run time. This course will teach you what they are, what they do, and how to make them work for you.
What you'll learn
Expression trees are an advanced approach to creating code, both at design time and at run time. In this course, Expression Trees in C#, you’ll learn about expressions and functions. First, you’ll explore the func delegate. Next, you’ll discover expressions you can compile to functions. Finally, you’ll learn how to construct extended expressions trees to get your work done. When you’re finished with this course, you’ll have the skills and knowledge of C# Expression trees needed to make your runtime compilation work.
